After assembling a rail to the bed, clean the surface of the rail and remove any oil2. Attach the ST tape slowly over the rail length to within 2 or 3 mm from each end of the rail3. It is strongly recommended to wear safety gloves, the edge of this tape is sharp and can cut asyou attach it to the rail4. After attachment to the rail, pressure wipe with dry cloth 3 or 4 times5. Tape should be applied 4 to 6 hours prior to rail usage to allow initial bondingOrdering example: SBG20ST - 2000Article No.Length2425

frictionLubrication AND GREASE NIPPLESFrictional ResistanceThe static and dynamic friction of SBC linear rail is so small that it can minimize the lost motion andtemperature increase.Frictional resistance depends on load, preload, velocity and lubrication.In general, light load with high speed is affected by the lubricant characteristic, and medium or heavy loadwith low speed.F =µP + fF : Frictional resistance(N)µ : Coefficient of frictionP : load(N)f : resistance with seal(N)If a seal is applied, seal resistance has to be added to the frictional resistance. The seal resistance variesaccording to its contact area, pressure and lubrication. When heavy load or preload is given to the block,the frictional resistance increases consequently.The above coefficient of friction doesn’t include the seal resistance.LubricationThe main purpose of lubrication is to prevent overheating by reducing friction and wear.To make the bearing efficient, the lubricant and lubricating method as well as load and velocity must beconsidered before hand. Regreasing for every 50.000 cycles, 50.000 meters or every 6 month is needed.In most cases, Alvania grease (AV2) is recommended.If a heavy load is applied, anti-pressure grease is suitable. A high load requires higher viscosity grease.In general, 13csT is proper to normal speed or light load, and 68csT to heavy load.Grease Fitting and Applied Model• If there is a pair of seals, 2~35(N) must be added according to each model number.Coefficient of Friction0,0150,010Coefficient of Friction µ0,00500 0,1 0,2*Load ratio (P/C)P: Load (N)C: Basic dynamic load rating (N)With sealNo seal2829

calculating the applied loadsCalculating the applied loadsCalculating the Applied LoadsCalculating the Applied LoadsLoads exerted on a linear rail system vary according to the location of gravity, line of force, changes ofspeed, etc. So it is important to consider these conditions before selecting type of linear rail system andmodel.

safety factors and calculation for mean loadlifetime calculationReference Values for Static Safety Factor (fs)In case of calculating a load exerted on the linear rail system, both mean load and maximum load arenecessary for calculating. Usually, reciprocating machines create unpredictable big load by force of inertia.When selecting the right linear rail system, check that it is suitable for the maximum load.Lifetime CalculationWhen using a linear rail system, not only the given load but also unpredictable vibrations and impacts mustbe taken into account. Hardness and heat can also be factors affecting life-time.CoPo≥fsfs : Static safety factorCo : Basic static load rating (N)Po : Impact load rating (N)3fH fT fC CL =( · ) · 50 (km)fWPCOperating conditions Load conditions fsL: Nominal life (km)C: Basic dynamic load rating(N)Pc: Load (N)fH:fT:fC:fW:Hardness factorTemperature factorContact factorLoad factorNormally stationaryNormally movingStep loadsImpact load or shaft deflection is small 1 ~ 1.3Impact or twisting load is applied 2 ~ 3Normal load is exerted or shaft deflection is small 1 ~ 1.3Impact or twisting load is applied 2.5 ~ 5Loads acting on a linear rail system vary according to various factors.

A table showing the individual block typesand whether an adapter plate is needed can be found on page 38.AN*Load Factor, fWFaUsually, reciprocating machines create vibrations that occur in high-speed operations, and such vibrationsare hard to be calculated precisely.
